JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 769,130, dated. August30, 1904.,

Original application filed March 14, 1903, Serial Ila-147,843. Dividedand this application filed March 12, 1904:. Serial No. 197,900. (Nomodeh) a subject of the King of Great Britain and Ireland, residing at 9Chatsworth road, Stratford, in the county of London, England, haveinvented certain new and useful Improvements in Journal-Boxes; and I dohereby declare the following to be afull, clear, and exact. de-

- the journal-box for the main axle, correspondto make and use the same.

scription of the invention, such as will enable others skilled in theart to which it appertains This invention relates to antifrictionmechanism as applied to the axle-shafts of railway carriages orvehicles; and it consists in a new or improved combination of partswhich are thought to have certain practical advantages, being a divisionof the application filed by me March 14:, 1903, Serial No. 1 17 ,843,and in order that my invention may be clearly understood and readilycarried into effect I will proceed to describe the same with referenceto the accompanying drawings, in which Figure 1 is a detail plan viewillustrating ing to which Fig. 2 is a transverse sectional view taken online w w of Fig. 1.

In the drawings a special feature of the journal-box 66 for the mainaxle I) is the construction of same, which must be of sufficient widthto allow the axle to pass freely into the box and is made with internalbearings 64 a on opposite sides of the axle-box, preferably in line withthe transverse diameter. These internal bearings or supports for thebrasses c c are of i the circular form shown and are made to fit theback parts of .thebrasses, which must not exceed the semicircle and inpractice are preferably rather less, the inside of the brasses beingmade to fit the main axle. The object of this bearings.

form of bearing is such that after the brasses are placed in positionthere can be no vertical or other dislocation of the main shaft, whichis held rigidly in respect to such movement,

but in rolling contact with the brasses until these are taken out, whichcan only be done by working them round the shaft clear of their thickerat the top end for taking up wear, which can be done by removing metalfrom the bottom, thus allowing the brasses to lower as thewear takesplace.

One advantage of this construction is that the brasses 0 are so shapedthat they can he slipped into place and that they Will retain theirposition by gravity and without the aid of supplemental fasteningdevices.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

The combination of a shaft and a support therefor, said supportincluding a journal-box provided with central projecting portions cutaway at their outer edges and sectional bearings of less extent than asemicircle provided with recessed portions adapted to fit theprojections on the box and with lugs adapted to fit into the cut-awayportions of the journal- The brasses are made slightlybox, said bearingsbeing fixed at the top and being adapted to be slipped into position inthe journal-box and to be held in place by gravity, without the aid ofsupplemental fastening devices, substantially as described.

In testimony whereof I afiix my signature in presence of llWOWliJHGSSGS.
